Altra Industrial Motion Dynaline Flexible Shaft Couplings
Guardian Couplings I Dynaline Flexible Shaft Couplings Why Choose Guardian? For more than 70 years, Guardian has been designing and manufacturing worldclass couplings and other power transmission components. Utilizing advanced manufacturing technologies and processes, Guardian provides highly-reliable coupling and component solutions to meet the most challenging industrial application requirements. DYNALINE FLEXIBLE SHAFT COUPLINGS Available in 4 sizes, the Dynaline is a single piece rubber-in-shear coupling. These couplings are used in sub-fractional thru 3HP applications, with torque ratings up to 54 IN-LBS. End fittings are made from zinc die castings, and are crimped to the rubber sleeve. Bore sizes up to 3/4 (19mm). The coupling length can be varied to suit many applications. Guardian provides a wide range of standard and custom products including flywheel couplings, hydraulic pump mounts, bearing supported stub shafts, flexible shaftto-shaft couplings, motion control couplings as well as compression pipe couplings. Durable Guardian products are utilized in key industries including mobile hydraulics, farm & ag, tree care, concrete, food & beverage, material handling, automation, power generation, and oil & gas on applications such as skid steers, aerial lifts, harvesters, wood chippers, concrete pumps, dewatering pumps, baggage handlers, conveyors, robotics, compressors, and generator sets. FEATURES & ADVANTAGES One-piece construction - No assembly, no wearing surfaces, easier installation. Corrosion-resistant end fittings are crimped to a neoprene sleeve to provide a maintenance free and longer life in difficult environments. Added length provides maximum angular and parallel misalignment. No need to align driver to driven components. Length to customer requirements. Neoprene sleeve provides a vibration free coupling which absorbs the shock of start-stop applications and peak overloads.

Altra Industrial Motion FL Flywheel Coupling/ Guardex TM Type FLD Pulley Coupling
Guardian Couplings I FL Flywheel Coupling FL FLYWHEEL COUPLING FEATURES AND ADVANTAGES MINIMUM SPACE The entire coupling length is normally mounted inside the flywheel housing face requiring only a flat pump mounting plate, saving valuable space inside the equipment frame. HEAT STABLE The glass reinforced nylon flywheel flange is designed to operate in diesel engine ambients without air circulation. It is dimensionally stable to 250 F. CROWNED GEAR TEETH The steel hub gear tooth design provides for angular misalignment, preventing angular forces on the pump shaft bearings and seals. FREE AXIAL TRAVEL The crowned steel hub teeth slide freely in the nylon flywheel gear teeth. Any shaft float is absorbed by the coupling and is not transmitted to the pump. ARRANGEMENT 1 Typical arrangement for SAE 6-1/2, SAE 7-1/2, and SAE 11-1/2 ENGINE SIDE Outside Bolt Circle Steel Hub Length OAL Flange Thickness Nylon Spline Length Steel Hub PUMP SIDE ARRANGEMENT 2 Typical arrangement for SAE 8 and SAE 10 ENGINE SIDE Outside Bolt Circle Steel Hub Length OAL Flange Thickness Nylon Spline Length Steel Hub PUMP SIDE BLIND ASSEMBLY In most assemblies, the steel hub gear passes through the pilot hole of the pump mounting plate.this allows for quick assembly without the need for a view or hand ports. *Consult Guardian for specific product installation instructions!

A l t r a I n d u s t r i a l M o t i o n Gear Grip
Guardian Couplings I Gear Grip GUARDIAN COUPLINGS GEAR GRIP APPLICATIONS The Gear Grip product is a general use coupling best suited for applications with a large degree of misalignment and is rated up to 50 HP. The Gear Grip coupling is a three-piece highly flexible design which includes two hubs and an elastic sleeve. Guardian offers three different sleeve materials including neoprene, urethane, and reinforced neoprene. Depending on the series, the hubs are typically offered in zinc or sintered steel. FEATURES & ADVANTAGES ALIGNMENT By-eye alignment eliminates precise measurement. This allows for a reduced assembly time and requires no special installation tools. Ideally, drive shafts should be aligned to minimize vibration and wear on the coupling and bearings. If excessive misalignment is unavoidable, the Gear Grip offers up to.090 parallel misalignment and 7.5 degrees of angular misalignment. TORSIONAL DAMPENING Neoprene and urethane rubber sleeve compounds provide excellent torsional vibration dampening. The load is distributed evenly over a wide splined contact area. This minimizes rubber deformation and wear while providing minimum backlash and wind-up. The Gear Grip coupling handles the shock, cycling loads, and vibration that produce extreme wear in other style of couplings. REFERENCE HUB REF: EZ: Zinc Die Cast End Fitting ES: Sintered Steel End Fitting SLEEVE REF: SM: Molded Rubber (92 Sh A) 250º F Max SR: Neoprene (85 Sh. A) 250º F Max SU: Urethane (95 A) 175º F Max SF: Reinforced Neoprene (85 A) 250º F Max IN-SHEAR DESIGN The in-shear design allows the coupling to act as a mechanical fuse in the event of an overload condition. This feature can provide protection to the expensive drive system. If the coupling were to fail, only the coupling sleeve would need to be replaced. ADJUSTABLE LENGTH The coupling length can be adjusted to meet the application requirements. This is obtained by using a longer sleeve. Please note, the torque may be lower for longer sleeve lengths, and the end-user should contact Guardian for proper specification. A wooden dowel or insert may be used for longer lengths to prevent the collapse of the coupling sleeve under the loading. Increased length may decrease the torque capacity, but it will improve the misalignment allowance and dampening. ENVIRONMENT This lightweight and compact coupling is not affected by moisture, dirt, or abrasives. The noncorrosive metal ends and rubber provide a long service life that does not require lubrication or maintenance. ELECTRICAL ISOLATION No possibility of metal-to-metal contact under severe overload, wear, or coupling failure. 1 www.guardiancouplings.com P-7915-GC 6/15

www.guardiancouplings.com CUSTOM / SPECIALS Guardian welcomes custom engineered designs. As part of our standard product offering we manufacture both inch and metric size bores with precision tolerances. Guardian strictly follows ANSI/AGMA 9002-B04 for inch bores and keyways. Metric bores conform to H7 tolerances and Js9 for the metric keyways. We manufacture a variety of custom solutions such as extended length assemblies, custom mounting, tapered bores, and various clamping options. EXTENDED LENGTH ASSEMBLIES Often times standard length couplings don t fit the application and longer lengths are required. The Gear Grip has the ability to work around the application. This coupling is able to extend up to 13.50. This versatile design can be fitted with an internal support to prevent the center from collapsing under load, while handling the power requirement and providing the necessary misalignment. CUSTOM MOUNTING Applications that require a custom mounting such as a pulley flywheel or clutch, the Gear Grip has a solution. Guardian can design and fabricate custom flanges and hubs to fit a variety of mounting systems. These can easily be adapted to the Gear Grip products. TAPERED SHAFTS Tapered bores can be machined with a straight or tapered keyway. It can also be fitted with a counterbore at the end of the hub for a locknut and washer if necessary. CROSS-CLAMPED HUBS Cross-clamped hubs can be offered for better clamping force to the shaft. In many cases vibration can lead to set screws backing out. Using Loctite and applying the proper seating torque, this feature can eliminate this common issue. There are several other clamping designs available.
